MACHINE FOR STAGKING HEEL-BLANKS.

Specification of Letters Patent.

Patented Mar. 3, 191st.

Application filed July 6, 1909. Serial No. 506,090.

To all whom it may concern:

lie it known that I, Josnrn ll. Porn, a citizen of the United States, residing at Fiouth llamilton, in the county of Essex and State of lllllSSilOllllSQilllS, have invented certain lmm-ovcmcnts in Machines for Stacking l-leel Blanks, of which the following description, in connection with the accompany inn drawings, is a specification, like reforcncc characters on the drawings indiating lihe parts in the several figures.

This invention relates to machines for stacking heel blanks. The present embodiment of the invention is illustrated herein as an improvement upon the machine shown in a prior applicationfor Letters Patent, Serial No. 3 1? ,5 10, filed December 19,, 1906. As will be apparent, however, lrom a consideration of the construction herein shown, many features thereof may be advantageously used in connection with machines of a different type from that described in said prior application. The inachine of said prior application includes a receiver which is adjustable in Width to accommodate blanks of different width and a carrier which receives blanks from a heel compressor and places them. on end in the receiver. The, machine of the prior application also includes means for positioning the blanks upon the carrier comprising guides with which the side edges of a blank have contact. The guides are mounted upon the carrier and are arranged for adjustment laterally thereon in order to accommodate lifts varying in Width.

fl. feature of the present invention consists in arranging; for simultaneous adjustment the side walls of the receiver and guides for positioning the blanks upon the carrier. According to the construction shown the guides are secured to the side walls of the receiver so that in adjusting" the receiver a proper :uljustnicnt of the guides is effected at the some time. independent adjustment of these d vices being: thus rendered unnecessary.

The {guides referred to are preferably connected Inovably with the side walls of the reccivcr and extend over and upon the blankrcrcivimz surface at the carrier in order that the guides may follow the carrier in its movcnurnla and always remain in proper relation therewith for maintaining a blank in correct position to be dclivm-cd to the reccircr. in the illustrated embodiment of the invention, also, a spring or other yielding device is arranged to act on the guides in order to hold them in contact with the currlcr during its movements from blank-rccciving: into blank-delivering position, and vice versa.

A further feature of the invention consists in means for restraining a blank from outwardly longitudinal movement upon the carrier 1n the movement of the carrier between its recelving' positionand delivering position. ,This feature is particularly useful where the blanks to be stacked are of considerable thickncssffor example, where they are heel blanks composed of a plurality of superposed lifts. This obviates any liability of a blank being forced outwardly by the pressure applied thereto by the carrier in advancing the contents of the receiver.

Other features of the invention, the advantages of which will be apparent to one skilled in the art, will be hereinafter described and referred to in the appended claims.

In the drawings,-Figure 1 is a View in perspective of a machine constituting one embodiment of the present in vontion; Fig. 2 is a view in vertical longitudinal section of the machine shown in Fig. 1; Fig. 3 is a top plan view of the carrier and parts immediately adjacent thereto shown in the preceding figures.

Referring to the drawings 1 indicates the head of a compressing machine which is antomatically raised and lowered as in the machine of the prior application referred to. The bracket 4 is secured to a rear face of the compressor frame, said bracket being provided with a horizontal bore in which is received a rod 6 extending rcarwardly from the bracket. Hubs 10 and 12 are mounted upon'the rod 6 and rigidly secured thereto. The hubs 10 and 12 arb provided with upward extensions to which the plate 16 form ing the bottom of the receiver is secured. The sides 18 and 20 of the receiver have secured thereto arms which are mounted upon the rod 6 and support the plates 18 and 20' in osition. The lower ends of the arms are ended as collars provided with segmental beveled gears, bevel gears being arranged upon the hubs 10, 12 between and in engagementwilh the segmental gcars'. Springs 36 and 37 are provided for pressing the sides 18 and 20 toward each other.

The construction thus far particularly described is substantially the same in. the

- prior application referred to and need not walls 18 and 20 may be conveniently se-' cured by inserting a blank in positioii be tween the side Walls the receiver.

A frame 1-0 is secured upon the rod '6 and is provided at. its upper end with bearings for a shaft 42. Secured to the central portion of the shaft 49 is a carrier 44.. The shalt 42 is provided with a quadrant at one end and a chain secured to said quadrzint and to the head 1, as in the machine of the prior application Guides 46 and lS'are pivotally mounted upon the side walls 18 and 520, respectively, for movement in planes parallel to the planes of said walls. A pin 50 is inserted in a pcrturcs"formed in the rear ends of the guides -16 and i8 and a rod 52 connects the pin 50 to one endof a spring 5 h the other end of which is comiected. to the hub 12. It will be seen that the spring S t applies force to the guides 1-6 and 48 tending to maintain them in contact.- Wilh the carrier (ll. The pressure of the guides 46 and 4-8 upon the carrier also serves to depress the carrier in the downward movement of the head 1. The carrier ti l is provided with. a shoulder, extending transversely across the same, formed by a removable to 56. It will be seen from Fig. 2 that as soon as the breast edge of a blank passes beyond the rear'edgc of plate'56 outward longitudinal movement of the blank is prevented. It will. be understood that such movement might be occa- Sionedby the engagement of a blank upon the carrier with the endmost blank in the receiver in the upward movement of the carrier. if desired the plate 56 may be removed to provide space for lifts of increased length. In that case-the shoulder formed upon the carricrl itself, as shown in F ig.

h, serves to prevent longitudinal. movement of the lifts. "The return with the carrier 44 of the blank inserted by said carrier in the receiver is prevented by vertical abutmcnts -57 inserted in the walls 18 and 20 approximately in line with the axis of the carrier ll.

In Fig. l the reference numeral 58 indi catcs the fingers of the ejecting mechanism which push a compressed blank from the top of the top lift plate ot the machine upon the carrier 44. in the ends of each linger 58 is arranged a rod 60 which is adjustable preliminary to filling transversely of the rod 60 and linger ig' '8 said.

cross bar 64: being held in place by a screw (36. It will be observed that this eonstruction permits the length of the fingers 58 to be varied. This may be desirable Where a considerable change occurs in the size of the blanks being operated upon; for example where the blank is quite small the length of the lingers 58 may be increased in order to insure that the blanks will be advanced far enough by said fingers to arrive in proper position upon the carrier 44-. It may also be desired to adjust the versely in order to arrange them the proper distance apart to accommodate the Width of the blank.

Having described my invention, What I claim as new and desire to secure by Letters Patent ol the United States is 1. In a machine of the class described, the con'ihination with a. receiver ad i width to accon'nnodate blanks varying in width, ot a carrier for supplying blanks successively to the receiver, and gnid gaging the sides ot a hlai'ilc to po 'tion it upon the carrier arranged :tor adjustment sin'iultfniconsly with the receiver.
